Why negatives matter more than ever
As match types have loosened, every keyword now reaches further than its wording suggests. That makes the list of things you do not want to appear for almost as important as the list of things you do. A good negative list is the difference between broad reach and broad waste.
Negatives are also the cheapest optimisation in paid search. They need no creative, no new pages and no bid changes. They simply stop money leaving the account for clicks that were never going to become customers.
Where negative keywords come from
There are two sources. The first is foresight: before launch, you can predict whole families of irrelevant searches. The second is evidence: once ads are live, the search terms report shows exactly which queries triggered your ads and what they cost. Foresight gets you started; evidence keeps you honest.
- Intent mismatches: 'jobs', 'careers', 'salary', 'course', 'definition', 'free', 'DIY', 'template'.
- Wrong product or service: the repair query when you only sell new, the rental query when you only sell outright.
- Wrong place: cities or regions you do not serve, if location targeting alone is not enough.
- Wrong buyer: 'for students', 'wholesale' or 'B2B' when you sell the other way.
- Research-only terms: 'what is', 'meaning', 'pdf', which often signal learning rather than buying.

From search terms to negatives
Sorting by cost matters. A long tail of one-click oddities is not where the money is. Start with the terms that spent most without converting, then work down until the remaining spend is too small to matter.
When deciding, focus on the root word that makes a query wrong, not the whole query. If 'accounting software jobs bangalore' is irrelevant, the problem is 'jobs'. Excluding the single word blocks every variant at once, which is better than excluding the full query and seeing a slightly different version next week.
Structuring negative lists

Three levels of negatives
Account-level and shared lists
Terms you never want anywhere: jobs, free, adult, competitor names if you choose not to bid on them.
Campaign level
Terms wrong for this campaign but right for another, such as brand terms in non-brand campaigns.
Ad group level
Terms used to route queries to the best ad group inside a campaign.
Shared lists save time and prevent the same exclusion being added inconsistently across many campaigns. Name them clearly ('Universal: employment', 'Universal: free and DIY'), apply them deliberately, and review them every quarter. Lists that nobody owns become lists that nobody trusts.
Using negatives to route traffic
Negatives can also steer queries between your own campaigns. If you run separate brand and non-brand campaigns, add your brand terms as negatives in the non-brand campaigns. If you have one ad group for 'emergency plumber' and another for 'plumber', add 'emergency' as a negative in the second so urgent searches see the urgent ad.
How negative match types behave
Negative keywords do not behave like positive keywords. Positive keywords match close variants, synonyms and related meanings. Negatives are more literal: a negative for 'job' may not block 'jobs'. Add plurals and common misspellings explicitly, and check current platform documentation because the rules differ between platforms and change over time.
| Negative type | Blocks | Watch out for |
|---|---|---|
| Negative broad | Searches containing all the negative terms, in any order | Does not block plurals or synonyms automatically |
| Negative phrase | Searches containing the exact phrase in that order | Extra words inside the phrase avoid the block |
| Negative exact | Only searches identical to the negative | Very narrow; used for surgical exclusions |
The mistakes that block good traffic
Myth vs reality
Negative keyword traps
The most damaging error is a negative that conflicts with a positive keyword, quietly stopping a campaign from serving. Most platforms flag such conflicts, but not always clearly. After adding a batch of negatives, check impression volume on your key campaigns over the following days.
A starter list to adapt, not copy
Every business needs its own list, but most share a few families of exclusions. Treat the families below as prompts. For each, ask whether the term could ever describe a buyer of yours; if it could, leave it out and let the data decide.
| Family | Example terms | Exclude when |
|---|---|---|
| Employment | jobs, careers, hiring, salary, internship | You are not recruiting through this campaign |
| Education | course, training, certification, syllabus, notes | You do not sell training |
| Free and DIY | free, DIY, template, crack, homemade | You only sell paid products or services |
| Second-hand | used, refurbished, second hand, rental | You only sell new or outright |
| Wrong geography | names of cities or states you do not serve | Location targeting alone lets them through |
| Support seekers | login, customer care number, complaint | Existing customers are clicking ads to find help |
The last family deserves a note. When existing customers click ads to reach support, you pay for traffic that organic results would have served for free. Excluding those terms, and making support easier to find on your site, fixes both the cost and the customer's frustration.
Negatives beyond Google Search
The same principle applies across paid media. Microsoft Advertising uses negative keywords in a similar way. Shopping campaigns depend on negatives because they have no positive keywords at all. Automated campaign types such as Performance Max offer more limited exclusion controls, so check what is currently available. On marketplaces such as Amazon Ads, negative keywords and negative product targets do the same job.

How negatives connect to the rest of the account
A strong negative list makes everything else work better. It lifts click-through rate by removing irrelevant impressions, which helps Quality Score. It gives automated bidding cleaner data. And it makes looser keyword match types safe enough to use. If you only have one spare hour a week for your account, spend it here.
Key takeaways
- 01Negative keywords stop ads showing for searches that will not become customers.
- 02The search terms report, sorted by cost, is the main source of new negatives.
- 03Exclude the root word that makes a query wrong, not the whole query.
- 04Negatives are more literal than positive keywords, so add plurals and misspellings.
- 05Over-excluding is as real a risk as under-excluding; justify every negative.
Frequently asked
- What are negative keywords in Google Ads?
- Negative keywords are words or phrases you add to a campaign or ad group to prevent your ads showing for searches that contain them. They remove irrelevant traffic, such as job seekers or people wanting free alternatives, so your budget goes to searches more likely to convert.
- How often should I add negative keywords?
- Review search terms weekly for a new or recently changed campaign, then fortnightly or monthly once the account is stable. Larger accounts and those using broad match need more frequent reviews because the range of matched queries is wider.
- Can negative keywords hurt performance?
- Yes, if they are too broad or conflict with your keywords. A single over-reaching negative can block valuable searches or stop a campaign serving. Base negatives on evidence, check conflict warnings and watch impression volume after adding a batch.
- Should I add competitor names as negatives?
- It depends on your strategy. If you have decided not to bid on competitor terms, adding them as negatives prevents broad match from showing your ads for those searches anyway. If you do bid on them, keep them in a separate campaign with its own budget and expectations.
- What is a negative keyword list?
- A negative keyword list is a shared set of negatives that can be applied to multiple campaigns at once. It saves time, keeps exclusions consistent and makes it easy to update universal exclusions in one place rather than in every campaign.
